2014 Silverado High Country with 6.2L. Has flow master dual exhaust. Some sort of tune was definitely loaded on it, because AFM has never kicked in. Going to take it to a friend’s shop and have them load their base tune onto it, because I don’t trust whatever is on there now. No power add on the tune they’ll do, but it disables AFM and does some other shit to make it drive a little better.
How’s the 6.2 pull from a roll? I drove one and the 8sp always felt confused of which gear to pick and took too long to down shift. Made it feel not that much more powerful than the 5.3. I ended up saving the cash and getting a 5.3, but also have the 8sp and its equally confused behind the 5.3 :picard:
Bc I don’t care about gas mileage and v8 noise for days. I do a lot of high way and I don’t want problems down the line with things not being lubed from v4 mode. I hear a lot of horror stories about people motors. Also installed catch can bc the DI oil blow by is real.
